These plans submitted by The Neve-Morin Group Inc., dated December 10, 2008 final revision date of January 22, 2009,have been approved for a four (4) bedroom, maximum nine-room home.

During this time a licensed septic system installer must obtain a permit and complete this work, and a Certificate of Compliance must be endorsed by the installer, designer and the Town of North Andover. This approval is subject to the following conditions: 1. If site conditions are found in the field to be different from those indicated on the design plan and/or soil evaluation, the originally issued Disposal System Construction Permit is void, installation shall stop, and the applicant shall reapply for a new Disposal Systems Construction Permit(3 10 CMR 15.020(1)). 2. It is the responsibility of the applicant and/or the applicant's septic system designer, septic system installer or other representative to ensure that all other state and municipal requirements are met. These may include review by the Conservation Commission,Zoning Board,Planning Board, Building Inspector,Plumbing Inspector and/or Electrical Inspector. The issuance of a Disposal System Construction Permit shall not construe and/or imply compliance with any of the aforementioned requirements. 1600 Osgood Street,North Andover,Massachusetts 01845 Phone 918.688.9540 Fax 978.688.8476 Web www.townofnorthandover.com Your effort to provide a properly functioning septic system for your dwelling is greatly appreciated.
